IOWA CITY, Ia. – The Twitter blew up late Saturday afternoon when word spread that Iowa running back Barkley Hill had to leave Kinnick Stadium on a golf cart after injuring something associated with his left leg.

The general theme: Here we go again.

The true freshman from Cedar Falls was hit while running into the end zone during a scrimmage at Kinnick Stadium, and the prognosis wasn’t revealed to reporters immediately after the nearly 3-hour workout.

“You hate it for any player,” offensive coordinator Greg Davis said. “Certainly Barkley is a young guy that’s impressed us. Hopefully it’s just a strain.”

Hill was injured on what likely would have been his final carry of the day, and in the final workout before classes start Monday.

He was among the players vying to be Damon Bullock’s backup at a position desperately in need of depth.

Other freshmen Greg Garmon and Michael Malloy were among the players showing their running back stuff, each playing at times with the first-team offense.

“We’re going to look at this film,” Davis said when asked if someone had emerged as a No. 2. “One of the reasons we wanted to let the young guys get as many rushes as we could was we wanted to see if they could protect the ball. We wanted to see who was going to break tackles and make plays, and who was going to handle the environment.”

The players worked out in game-like conditions that included rock concert-like music, and crowd noise louder than they’ll hear at most venues. Coach Kirk Ferentz wore a headset on the sidelines, like he does during games. Coaches worked in the press box and on the field.

Garmon and Hill, in that order according to most reporters watching from the stands, are the two most likely second-team considerations.

Davis said the decision could be made by Monday. It could happen sooner if Hill’s injury is serious.

The top two receivers, Keenan Davis and Kevonte Martin-Manley, were withheld. Greg Davis said both are expected to return to practice soon.

“I think we’ll be fine,” Davis said.

Starting linebacker James Morris didn’t play, either, although he was in uniform. He had a wrap on a thumb.

Defensive coordinator Phil Parker said Morris could return to practice on Tuesday.
